Specicationo'f Letters "Patent 1\T o. 1-2,'089,dafte December 19, 18521.

To all whom Sitz may concern? Be it known that .'I, SAMUEL W. BROWN, fofLow'ell, in the Icounty of Middlesex fand Commonwealth of Massachusetts,have invented a l*new and useful Condenser; and I -do thereby declarethat thel following is a full, clear, andfexact description of @theconstrue-'tion and 'operation of .the same, refer- 'ence being had 'to"the accompanying ldrawings, ina'king part of this specification, inWhi'clil l Y Figure l, isan elevation and Fig 2 a vertical section ofthe'same. Fig. 3, 1s a vertical section of a device diiiering from Figs.

l and 2, and Fig. 4, iis also a -part verticalr section of a devicediffering fromfeither of the other iigures, and which I believe to bethe most simple in construction andthe best of either of the otherdevices hereafter specified.

The letters refer to like parts as far as the said parts are similar, inall of the views of the said drawings.

The nature of my invention consists in an arrangement of a condenser,attached to the end of a steam pipe, with an orifice at each end of thesame, and in the lower orifice is fitted the lever valve seat and to thesaid seat is fitted a valve, so that'as the said condenser which isattached to the pipe, which forms a spring for the same, descends Abythe weight of the water of condensation which has accumulated, until thevalve lever strikes against the top of the discharge pipe as seen inFig. 2. or on the stand H Fig. 3, or the lever F Fig. 4, which opens thesaid valve in the bottom of the condenser and permits the condensedsteam or water to discharge itself below and still prevent the steamfrom escaping.

To enable persons skilled in the art of making steam condensers to make,construct, and use my invention, I will describe the vsame as follows. l

First I construct a condenser the cylinder of which is seen at, A, AFigs. l and 2, and in sections at Figs. 2, 3,A and 4, of the drawing. AtB Figs. l, and 2, can be seen the steam pipe the end of which isattached to the said cylinder. nAt C Figs. 2, 3, and 4 can be seen thelever valve which I design to place where it necessary to operate as avalve simply, that is to move upward and downward nearly vertically bythe stop coming direct-ly in contact with-the same,

when the condenser '.i'sjdepressed instead of A rcoinmg lin contact'with the `inclined Vsur- `faces as -seen in "the threejdevices of thedrawing. And 'at 'D 1 @and 2, jean --be seen lthe ylever valve seat, fatE Figs. 1, 2,8, F :and y4, fis shown the "dis-charge p'ipesby which lthesurplus ywater 'esca es.

Ilhe fcon'den'sers v'can zbe 'ma' e of cast iron, but for the valvelever and seat, bronz'e would be preferable for'dfurabi'lity. Theobjectof vhanging the aforesaid condenserfto #the steam pipe is for the,purposcof making the fsaid pipe answer the purpose of a fsp'r-iingfandat the 'saine time forv the water to pass 'through `and offdispensingwith la oa't 1n the condenser sotliat fasthe water taccumulates asbefore mentioned that the said condenser will descend until the levervalve comes in contact with the projection from the top of the dischargepipe as seen at Fig. 2, or. with the stand H, Fig. 3, or the lever F,Fig. 4, of the drawings, then the said valve will commence opening anddischarge the water below until it is nearly exhausted, then the saidcondenser being properly ladof the pipe which will-shut the valve and so'remain until the water again accumulates sufficiently to depress the,condenser as before described and referred to in the drawings.

I do not confnemyself to any particular form in carrying out myinvention, but the form and manner of constructing them as shown in t-hethreeI separate devices of the drawing are all perfectly effectual.- Thedevice as shown at Fig. 3, consists of a stand H, screwed to thedischarge pipe and guide pulley I to guide the condenser as it moves upand down. But the device shown in Fig. 4, is the cheapest, simplest andbest way of making them, and also perfectly effectual for the signed.

It consists of the lever F, and projecting ear G, as seen at Fig. 4, andthe out end of the lever F, resting on the discharge pipe E, Fig. 4, sothat as the condenser descends the valve will be opened with much lessweight of water than it could be by the devices ,shown in Figs. 2 and 3,so that the condensers made in this way can be much less in size thaneither, of the other devices.

For ordinary purposes the cylinder may be the full size as indicated inthe drawing,

'justed as to weight -will rise by the spring purposes for which it isde- 2O .x-hereby, disclaim a valve as such the end of and cast wholeexcept an orifice or hole at each end for the purpose of resting thecore in casting them and also for screwing in the valve seat D, andsteam pipe B, the opposite hole from where the valve seat is placed canbe used for admitting the pipe, or otherwise it is stopped with a castiron plug, and the steam pipe can be attached to the cylinder at thebosh J, Figs. 1 and 2, of the drawing.

It will be most convenient to attach the `condensers to the pipe,letting them, the pipes, be secured into the bosh J, instead of curvingthe pipe as shown in the drawing, the operation being simply by lettingthe steam into the pipe, and therefore I do not deem it necessary toexplain farther on that point as it has been alluded to in the draw ingand in describing the construction ofv them,

Having thus' described my invention I which comes directly. in contactwith a flat stationary projection which hoists the whole surface of thevalve at once as is operated by excess feed water apparatus designed tobe used in steam boilers.

What I claim as my invention, and desire to secure by Letters Patent isl. The lever valve C, in-combination with the incline plane on the topof the movable lever F, or with a stationary incline plane, for thepurpose of opening this lever valve C with an increased power, when thecondenser descends by the yielding of the tube to which it is attached,this yielding being caused by the weight of the water of condensation,the valves and surfaces to open them being constructed and operatedessentially in the manner and for the purposes set forth.

2. I claim suspending the condenser by a Y tube of metal or othersubstance so remote from the bearing on which this tube rests that itwill yield or spring downward by the weight of thewater of condensationsufficiently to open a valve or its equivalent which allows ofthe escapeof this water and retains the steam.
